Tumor de células de leydig: presentación de ocho casos y revisión de la literatura

Leydig cell tumor is the most frecuent non-germ cell tumors of testis, included in the group of specialized gonadal stromal neoplasms. It has a low incidence, accounting for 1-3% of testicular neoplasms. This tumor is characterized by its endocrine manifestations, due to the tumor´s capacity to secrete hormones.We report eight cases, including the description of their clinical, diagnosis and therapeutic features, as well as their follow-up. We also make a review of the literature about this rare testicular tumor.

Non-germ cell tumors of testis

Testicular tumors of non-germ cell origin represent from 5 percent to 10 percent of all testicular neoplasms. Included in this group are sex cord/gonadal stromal tumors, most originating from Leydig or Sertoli cells, mixed tumors, and tumors of mesenchymal or hematopoietic origin. In addition, various miscellaneous lesions, tumor-like conditions, and secondary testicular tumors may be classified as non-germ cell tumors. This review covers the presentation, diagnosis, and treatment of these rare lesions.
